PAMPHLET-COVEBER.

Application filed March 21, 1914. Serial No. 826,451.

Be'it known that I, GEoRo Srmss, a sub ject\ of the Emperor of Germany,residing in Leipzig-Reudnitz, Germany, have invented certain newanduseful Improvements in PamphleaCoverers, of which the following is aspecification. I I 3 It is important for the successfuloperation ofpamphlet covering machines that the individual sheets which go to makeup a pile, be presented tothe glue coated cove'r in such manner thateach and everysheet willbe uniformly brought in contact therewith so asto be securely glued thereto.

Now' according to this invention it is proposed'to attain'thi'sobject bythe provision at the end of the sheet feed conveyer of-oscillatingmembers which are journaled so as to be brought by oscillating movementalternately into the plane of the'path of'the sheet piles and to beerected vertically or approximately so if desired. The parts of amachine of this kind necessary for the understanding of this inventionare illustrated by way of eXamplein the accompanying drawings, in whichFigure l is an elevation, Fig; 2 a lateral view of the machine,'and Fig.3 is a lateral view of the delivery device of thesame.

The individual sheet piles A arefed forward by a conveyor B atcertainpredetere.

mined or definite intervals. According to this invention plates or armsC are flexibly "arranged at the end of this conveyer B so as to becapable of being loweredbetween the conveyer bands and thereby to bebrought into the path or track of the sheet piles. As soon as a pile Aarrives above these, plates G the latter are tripped up into thevertical position indicated in dotted lines wherebythe pile is caused todrop vertically on to a cover D which previously has had its back coatedwith glue and has been placed on a supporting table E, E The plates Care caused to oscillate about theirpivots by means of an eccentric Cwhich is coupled through the links C and G to the shaft upon which theyare carried. 7 In this action the freely dropping sheets of the pile Aare individually seated on the glued back of the cover thereby insuringa'sound connection with the glued part. In their movement the droppingpaper piles are guided between vertical walls F and G. For thecompletion of the pamphlet, roller pairs may in a known manner he usedby which is caused to be pressed against the paper pile. To this end, inthe example shown, the

the P Penpile together with th glueaflfi over is carrie d downandifinally the cover rollers H and J 'aregarranged above the table E, Ethe roller H being movable to-' ward the roller J. This, may be effectedwith the aid ofj'a bell" crank leverK actuated'by a connecting rod Lwhich bymeans of a roller N is guided on; acam'disk- My ar ranged on thedriving shaft. By means 'of these rollers the/paper pile A after beingseated on the, "cover D is caused to move downward with the cover foldedthereon; Beneath the passage in the'table are -ar ranged further rollerpairs 0, P and Q, R,

of which 0 and Q, are relatively movable "with regard to the stationaryrollers P and B respectively, similar to the rollers H and ,J. Now thearrangement is such that the rollersI-I, O and Q are consecutively given.a lateral displacement and that only those rollersare always operativewhich for the time being are to act on the pamphlet. The movement oftherollers O and Q, is efiected by similar means, namely, by bell cranklevers K, K with the aid-of connecting rods I], L driven by cam disks MM respect1vely,*which latterare mounted; on the samedriving shaft thatcarries the cam M.v

In this way the descendingpamphlet is'first compressed between therollers O, P and as it advances between thebands S, T,=it is broughtbetween the rollers Q, and {R by which it is delivered to a support U.At this point the individual covered paper piles or pamphlets arefinally compressed between a movable plate or jaw V and a sta tionarycounter-platefor abutment V.

In the case of heavy and thickpaper piles and weak or thin covers, there1s a danger that the dropping paper piles pull down the covering Dbefore the rollers H and J have approached one another. To counteractthis, a movable plate or obturator W is arranged below the passage inthe table. This plate s I may, for instance, be carried in guides on oneof the table leaves E so that it may be advanced in order to cover thepassage between these table parts. In this case the paper piles indropping on to the back of the cover D press the latter against theplate'W at the same time themselves assuming an upright position wherebythe back of g each sheet is reliably brought into contact with a gluedpart of the back of the cover. The

surfaces of the plate W may be roughened,

- at the point U a presser band Y guided over rollersZ' is so arrangedas to travel in the direction'of; the back of the cover and thereby toexert a presse'r action on the backlongitudinally in order again toforce the glue to penetrate between the adjacent edges of the individualsheets. Moreover, this strok ing arrangement insures a uniformd1str1bu-- tion of the glue at the connecting points and the band Y usedfor'this 'purpose may consist ofrubber'or other-elastic material.

e What I claimand desire to secure by Letters Patent is l. A- pamphletcovering machine comprising in combination asheet pile conveyer,'asupporting table upon which a glued pamphlet cover is carried, an:oscillating plate adapted to remove the sheet'pile frornsaid conveyorand direct it onto the said cover,
